Key Benefits
Performance
Enhanced Layer 2 10/100/1000 LAN
switching solution delivers wirespeed
Gigabit performance. 48 built-in
copper Gigabit ports, including four
dual-purpose ports supporting
copper links or SFP adapters for
flexible connection to fiber-based
Gigabit media.

Port-based rate-limiting enables the
bandwidth on each port to be
restricted, so power users can receive
the full bandwidth available while
non-key users can be throttled down,
preserving network bandwidth and
allowing maximum control of
network resources. Built-in packet
prioritization gives optimal
performance to real-time applications
such as voice and video.

Future Protection
Gigabit to the desk prepares your
network for the future at prices
comparable to those of some 10/100
switches. Tri-speed operation at 10-,
100-, and 1000Mbps allows easy
migration to Gigabit speeds.

Investment protection is further
enhanced with switching silicon
designed to support multilayer
switching.

Ease of Use
Automatic selection of the optimal
speed and duplex mode of cables
connected to it prevent mis-configu-
ration of the network. The switch
also detects and adjusts to cross-over
or straight-through cable connections—
a feature called auto MDI/MDIX—
eliminating the need for specific
cables.

Security
IEEE 802.1X network login enables
intrusion prevention on the network,
requiring users to authenticate with a
central standards-based RADIUS
server for ease of management;
unauthorized users are kept off the
network.

Management of the switch can be
implemented using Secure Shell (SSH)
and Secure Sockets Layer (SSL /
HTTPS) encryption, preventing
unauthorized remote access to the
switch over IP networks or from a
web browser.

Network Control
Network management can be done
through the embedded web interface,
command line interface, or an SNMP
management station. This can be
further simplified with the use of
3Com Network Supervisor for config-
uration and troubleshooting of
multiple devices on the network.
